Abstract		Root canal irrigation is a component of the endodontic triad. The most common endodontic irrigants are saline solution, ethylenediaminetetraacetic acid (EDTA), 3% hydrogen peroxide and 2.5% sodium hypochlorite. Saline solution provides mechanical rinsing only. It is used in immunocompromised and hypersensitive patients, and in order to neutralize other fluids present in the root canal and periapical region. EDTA binds calcium ions and causes softening of dentine. It also provides mechanical rinsing. No complications have been reported in connection with its use. Hydrogen peroxide releases oxygen when in contact with tissues. It acts as a disinfectant and has a mechanical rinsing effect. When used in excessive quantities, it may cause air emphysema. Potassium hypochlorite is the irrigant of choice for root canal irrigation: it disinfects the root canal and dissolves organic material. Complications associated with its use include hypersensitivity reactions and irritation of the oral mucosa. Inadvertent handling may cause damage to the patient's eyes and discoloration of clothing. The complications are prevented with a detailed history, the use of a rubber dam and appropriate irrigation technique.
Summary		Izpiranje koreninskih kanalov je sestavni del endodontskega triasa. V ta namen uporabljamo fiziološko raztopino, etilendiamintetraocetno kislino (EDTA), 3-odstotni vodikov peroksid in 2,5-odstotni natrijev hipoklorit. Fiziološka raztopina ima samo mehanskoizplakovalni učinek. Indicirana je vedno, kadar imamo opravka z imunsko kompromitiranim ali preobčutljivim bolnikom in za nevtralizacijo drugih tekočin v koreninskem kanalu in periapeksu. EDTA ob stiku z zobovino veže kalcijeve ione in mehča dentinsko tkivo. Pri izpiranju izrabljamo tudi mehanskoizplakovalni učinek. Zapleti pri njeni uporabi niso znani. 3-odstotni vodikov peroksid sprošča ob stiku s tkivom atomarni kisik, ki ima dezinfekcijski in mehanskosplakovalni učinek. Spiranje kanala čez apeks lahko povzroči zračni emfizem. 2,5-odstotni natrijev hipoklorit je irigant izbora: dezinficira koreninski kanal in topi organske snovi. Možni zapleti uporabe hipoklorita so: razbarvanje bolnikove obleke, draženje ustne sluznice, nenamerna kanitev hipoklorita v oko, preobčutljivostna reakcija bolnika na hipoklorit. Anamneza, pravilna tehnika izpiranja in uporaba koferdama preprečujejo zaplete.
